“…This means that if the cost of solvent extraction is considered, the optimum conditions must be used. The nominal oil yield after this optimum point bears a negative cost on the overall extraction cost (Efeovbokhan et al, 2015). The experimental extraction oil percentages of Moringa oleifera from Cuba were 40.12, 40.56 and 42.48%.…”

“…The slope of the line was used to estimate the effective diffusion coefficient. An initial oil content (c 0 ) of 45% was considered since it is the maximum reported by Abdulkareem et al (2011); Ayerza (2011) and Efeovbokhan et al (2015) for Moringa oleifera. The equivalent radius of the sphere was taken as the average radius of the particle conglomerate obtained by the sieving operation.…”

“…The freshly charged solvents (lean oil) created a positive gradient or the needed driving force that resulted in a higher mass transfer rate of oil in to the extracting solvents. After the optimum point had been reached, the extracting solvents (oil rich) gave rise to lower driving force or slower extraction rates (Efeovbokhan et al, 2015). The experimental kinetics of the extractive process were required to determine the effective diffusivity coefficient.…”

Moringa oleifera is an oilseed crop with potential for biodiesel production. The second step in this process is the extraction of oil. Extraction in hot water, with a Soxhlet apparatus and the ultrasound technique are the most commonly used methods. The aim of the present work was to obtain a phenomenological model for the Moringa oleifera oil extraction process using Soxhlet. Effective diffusivity for Moringa oil through the kernels is obtained, using the kinetics of the extraction process (experimentally determined) and the Fick’s diffusion second law for non-steady state. The value of 0.685·10-12 m2/s fully matched reports on effective diffusion coefficient for other solids. It was also verified from the statistical analysis and a linear fit for experimental data that the model can be used to describe the oil extraction process of Moringa oleifera in the Soxhlet extractor, responding to the diffusive phenomenon (process controlled by internal resistance).

“…Efeovbokhan 19 in his investigation to study the effect of different solvents on composition of Moringa oleifera seed's oil referred to the presence of different percentage of palmitolic acid in the seed oil extracted by different solvents. Furthermore, it was reported that oleic acid present in crude extract of Moringa oleifera seed oil 20,21 .…”

Moringa oleifera is one of the most important and useful plants because it is both a medical and nutritional plant. The aim of this study is to determine the antioxidant and antibacterial activity of Moringa oleifera seed oil extract. Petroleum ether solvent in Soxhlet apparatus was used to prepare the seed oil. Many tests were conducted included, Gas Chromatography-Mass Spectrum (GC-MS), evaluation of antioxidant activity utilizing 2,2-diphenyl-1-picrylhydrazyl (DPPH) assay, total phenolic content. The oil extract of Moringa oleifera was investigated against some foodborne pathogens include Staphylococcus aureus, Bacillus cereus, Escherichia coli and Klebsiella pneumonia. The results of GC-MS revealed to the identification of twenty two components, the prevalent compounds were Oleic acid (14.61 %), Butyric acid (11.55 %), 8-Octadecenoic acid, methyl ester (11.16 %) and 1-Pentanol (10.75 %). The radical scavenging activity of the seed oil was 75.81% in concentration 100 µl/ml, and the (EC 50 ) was 25 µl \ml. Furthermore, the total phenolic content of the seed oil extract increased gradually with the increases of concentration. The results of the antibacterial activity of Moringa oleifera oil extract showed that the oil extract have the antibacterial effect against all tested bacteria in all concentrations except E. coli and K. pneumonia which were resistant to the seed's oil extract in concentration 125 µl/ml. The highest antibacterial activity was observed on Staph. aureus, B. cereus, E. coli and K. pneumonia with inhibition zone 18.50, 14.16, 11.83 and 11.33 mm in concentration 500 µl/ml respectively. Furthermore, the MIC of the oil extract was 64µl/ml for Staph. aureus, 128 µl/ml for Bacillus cereus and 256 µl/ml for each E. coli and K. pneumonia.

“…It is found petroleum ether solvent can detect the compound in lower retention time (Figure 1, Figure 2, Figure 3, Figure 4 and Figure 5). According to Efeovbokhan et al (2015), petroleum ether solvent gave the highest oil yield from Moringa seed followed by hexane then isopropyl alcohol. The comparison of five extracts in terms of the identified compounds, derivatives, and the predicted activity are listed in Table 2.…”

Chemical compounds of wood preservation from plants vary and are not known specific to the species. Chemical analysis of plants is responsible to ensure active compound in natural extracts wood treatment. There are many sources of natural extracts found in Indonesia that were explored for wood preservatives chemicals. They are bark of acacia and alstonia, leaves of orthosiphon and azardirachta and Dioscorea tubers. The present study was aimed at investigating the variation of the chemical constituent of natural extracts material of wood preservative through GC-MS analysis. Five natural extract sources were acacia bark (Acacia spp.), pulai bark (Alstonia scholaris), kumis kucing leaves (Orthosiphon spp.), mimba leaves (Azardirachta indica), and gadung tubers (Dioscorea spp.). Two non-polar solvents, i.e., n-hexane and petroleum ether were used for five natural source extractions following ASTM soxhlet extraction. The research showed that triterpene and fatty acid derivatives were the major compounds present in five natural extracts.
